Alpheus Todd

Alpheus Todd CMG FRSC (July 30, 1821 – January 22, 1884) was an English-born Canadian librarian and constitutional historian, most notable for his publications on parliamentary government.

In 1835, Sullivan helped Todd obtain employment in the library of the House of Assembly of Upper Canada; in 1836 he became assistant librarian.

When, in 1841, Upper and Lower Canada were merged, Todd was appointed assistant librarian to the Legislative Assembly of the united province, which adopted his Practice and Privileges as an official guide for members.

Notably, the Parliamentary Library survived "because of the foresight of librarian Alpheus Todd and clerk Connie MacCormac.

Together, they had one daughter and four sons, one of whom, Arthur Hamlyn Todd, published second editions of his father's two works on Parliamentary Government, and left an unpublished life of him.
